No way this could be a spoiler.

I do believe that Blake is my favorite.  I can see why you said what you did about her development, Plank, but I enjoyed it more than Jaune's constant blundering.  It's not totally necessary in my eyes to see a character change cell by cell; witnessing the final product and understanding what took her there is fine for me.  Blake definitely interests me the most out of the main four.

I do agree about the fight though.  I was waiting for someone to do something cool (bringing opponents in from around the world is a great opportunity to get really creative and awesome!) but only Reese and Arslan did remotely anything and the others made me more disappointed in Remnant's average manliness level.  Hopefully they'll put up foes more entertaining than funny-haired punching bags in the future.
